Abstract
PURPOSE: To make it possible to reproduce pictures correctly by providing a filter consisting of elastic surface wave element SWA, a variable gain circuit and a deviation value detector circuit in a color TV receiver.
CONSTITUTION: TV signals applied from tuner 2 to SAW filter 3 are applied from control circuit 4 to amplifier circuit 5 and pass through detector circuit 6 and are supplied to Braun tube 8 through processing circuit 7, thereby reproducing a picture. The amplitude level of the chrominance subcarrier in signals is detected from the output of circuit 7 at a color TV broadcast receiving time by deviation value detector circuit 9, and a DC control signal is generated according to the amplitude level and is applied to circuit 4. Circuit 4 is combined with SAW filter 3 and is operated to control the frequency characteristic of TV signals of the intermediate frequency, which is sent from tuner 2 to circuit 5, according to control signals from circuit 9, so that TV signals of a correct frequency characteristic can be obtained from circuit 6.
